action of steam at 290 C. and a pressure of 65 atm. .Said alloy is made of 5 parts lead, 1 part antimony and A part zinc. The proportion of said constituents may be somewhat modified, but the named one gives the best results.

It has been found that such a packing resists not only to high temperatures and pressures, but also the action of acids which may be containeg in the steam, and has the advantage of n ver splitting or breaking Application filed October 22, 1927. Serial No. 228,077.

along the ed e, nor crumbling to pieces at the points o highest pressure. This prevents obstructionof the piping.

The new alloy can also be us? for gaskets, for instance in flange join s of steam pipings, as substitute for theordinary asbestos or klingerit and the like packings. Owing to the hardness of the alloy being lower than the hardness of the joined metal parts, said latter force their way into the packing, thereby ensuring a most per- I fect tightness.

I claim: I

1. Alloy for joint packings and the like, composed of 5 parts lead, 1 part antimony and part zinc.

2. Asa new article of manufacture, a gasket for making joints for waive-cocks, pipes, and the like made of an alloy composed of 5 parts lead, 1 part antimony and part zinc.

In testimony whereof I sign hereunto my name;
